2006 Chevrolet Monte Carlo Preview

save on fuel. When the vehicle is under light loads, meaning it isn't coaxing a trailer or fully loaded cabin and trunk up a steep hill or isn't at full throttle, four of the engine's eight cylinders go into hibernation. The system allows up to 12 percent savings in fuel, which should make a difference in the pocketbook considering today's exorbitant gasoline prices. The transition from eight to four and then four to eight cylinders is virtually seamless, and full power is available at the touch of the throttle, so its one of those rare "have your cake and eat it too" benefits.

Splitting the base and top engine choices is a 240-horsepower 3.9L V6 with 245 lb-ft of torque, based on the same architecture as the 3.5L V6.

GM combines all engines with its well-proven Hydra-Matic 4T65-E electronically controlled 4-speed automatic transmission, for smooth shifts and durable performance. While this

is a well-proven gearbox, most of GM's competition is offering five- and even six-speed automatic transmissions, the extra gears enhancing performance and fuel economy.

Power without control would be utterly wasted, so therefore GM has upgraded the Monte Carlo's suspension system to allow what the automaker refers to as "more confident ride and handling characteristics."

Of course, the Monte models will ride quiet and smooth too, paramount for any large, midsize car. It receives a heavier duty front-end structure, reducing noise vibration and harshness (NVH) levels and enhancing control through corners or during emergency evasive maneuvers.
